Offset was supposed to be in Toronto last night performing with Drake and the rest of the Migos.

But their show had postponed, allowing Set to jet down to New York and watch his wife Cardi B open the VMAs.

Cardi didn't have much a monologue.  But she did joke like she was about to reveal their infant girl Kulture to the crowd.  The punchline was she was actually cuddling an MTV Moonman statue, not a little baby.

Offset didn't much appreciate the high profile prank.

Why Set said i was sooo mad, when i saw you on stage with that blanket 😩I thought you was going to show Kulture 😩😩😂😂😂😩
